EMGs (Electromyography Studies)

Electromyography (EMG) is a test that measures the electrical activity of your muscles to see how well they respond to nerve signals. At University Spine Center, our specialists, including Dr.Sophia Yae,DO, use EMG testing to identify the cause of muscle weakness, numbness, or pain and to detect any underlying nerve or muscle issues.

Why EMG Testing Is Important

EMG helps doctors diagnose nerve compression, nerve injuries, and neuromuscular disorders. It is also used to evaluate chronic pain affecting the arms, legs, or spine. By providing clear, objective information about how muscles and nerves are functioning, EMG allows your care team to create a precise and effective treatment plan.

What to Expect

During an EMG test, small electrodes are placed on your skin, and a thin needle electrode may be gently inserted into certain muscles. The test records the electrical activity when muscles are at rest and when they contract. Most patients feel only mild discomfort during the needle placement. The procedure usually takes 30 to 60 minutes, depending on the number of muscles tested.

Safety & Recovery Tips

• EMG testing is generally safe and minimally invasive.
• Some patients may experience slight soreness or bruising where the needles were inserted, but this usually goes away quickly.
• There is no downtime, and you can return to normal activities immediately after the test.
• Follow any instructions from your care team and report any unusual symptoms if they occur.

EMG testing at University Spine Center provides a clear understanding of muscle and nerve function, helping doctors target treatments that relieve pain, restore strength, and improve daily function.
